Graph ► Tasks ► Set Of Scalars

The Set Of Scalars task shows, among other things, bar graphs. Here are a few things to note about this task:

Data is defined like this: { {s_1,1, s_2,1, ... s_n1,1} , {s_1,2, s_2,2, ... s_n2,2} ... {s_1,m, s_2,m, ... s_nm,m} }. Translation: Form a sequence of scalars (denoted by s_i,j where i is the sequence index) and then form a sequence of sequence of scalars (where j is the set element index and an element of the set is a sequence of scalars). The "sequence of scalars" is called simply "scalars" or an element of the set of scalars, hence the name Set Of Scalars. An element is defined as a particular sequence in the set.
Scalars are not entered in set or sequence notation. Rather each sequence of scalars are entered separately as a list of delimited numbers.
Stacked bars are the summation, at each element index, of successive groups of data, while offset bars show absolute values.
Pie charts show one group of data at a time. To pan groups touch and drag across the pie graph. Similarly with other representations.
The Edit Graph, and its skins, can be used to add distinction to the presentation such as bar gradients.

Data Importing and Exporting Formats

The Table Editor atomic cell type is a textual value for column one and a scalar value otherwise. For column one, label elements must be separated by a return character delimiter while using column and block-select import. For all other columns, column, row and block-select import format is a list of scalars separated by a delimiter.
The Edit Data (available in Developer Mode only) format is an ordered list of numbers separated by a blank. Each bar group (scalar sequence) is entered by first assigning a number from 1-20 in the textual row entry (corresponding to the element index in the set) and then navigating to that group's editing tool. 1 is the default and will do for a simple bar chart. To edit labels use 0 or l in the textual row entry.
The Fetch Data (available in Developer Mode only) format is an ordered list of numbers separated by a blank or an XML structure.

Representations

The Set Of Scalars tasks implements the representations described in the following table. Remember that Skins can affect the representation and may even alter the representation to not conform to the following descriptions.

Representation	Description
Bar > Offset > Half	Shows a usual bar chart which has the following attributes: The bars are half the distance from each other, lengths oriented horizontally and sets of scalars are represented by successive offsets from the label for the particular scalar sequence index. The y-axis label is an integer or if the number of bars is too great then sparse integers unless (custom) labels are assigned.
Bar > Offset > Full	Same as Bar > Offset > Half except the bars touch each other.
Bar > Stacked > Half	Shows a stacked bar chart which has the following attributes: The bars are half the distance from each other, lengths oriented horizontally and sets of scalars are represented by successive summation of values for the particular scalar sequence index. The y-axis label is an integer or if the number of bars is too great then sparse integers unless (custom) labels are assigned.
Bar > Offset > Full	Same as Bar > Stacked > Half except the bars touch each other.
Column > Offset > Half	Shows a usual column chart which has the following attributes: The bars are half the distance from each other, lengths oriented vertically and sets of scalars are represented by successive offsets from the label for the particular scalar sequence index. The x-axis label is an integer or if the number of bars is too great then sparse integers unless (custom) labels are assigned.
Column > Offset > Full	Same as Column > Offset > Half except the bars touch each other.
Column > Stacked > Half	Shows a stacked bar chart which has the following attributes: The bars are half the distance from each other, lengths oriented vertically and sets of scalars are represented by successive summation of values for the particular scalar sequence index. The x-axis label is an integer or if the number of bars is too great then sparse integers unless (custom) labels are assigned.
Column > Offset > Full	Same as Column > Stacked > Half except the bars touch each other.
Pie Chart	Each set element of sequence of numbers is represented by a pie chart where each wedge has a arc-length proportional to the scaler it represents divide by the sum of scalars in the sequence. Note that only one pie chart can be shown at a time. In the case where there is more than one element of scalars then pan through the set by touch drag from left to right.
